It also includes a driving module for driving the slider 4 to slide up and down along the supporting slide bar 3. The driving module can be a motor, a cylinder or a memory alloy part, etc. The driving module of this embodiment is a memory alloy part 7. The memory alloy part 7 drives the slider 4 to slide relatively along the supporting slide bar 3. One end of the memory alloy part 7 is fixedly connected to the lower end of the slider 4, and the other end is connected to the base 1.

[0028] It should be noted that the memory alloy part 7 is made of a memory alloy material, preferably a nickel-titanium alloy, which has the characteristics of generating memory deformation when heated and recovering after heat dissipation, and has the function of mechanical driving. The memory alloy part 7 in this embodiment generates memory deformation by connecting an external power supply, and can also generate memory deformation by heating the memory alloy part 7 through a heating module. The shape of the memory alloy part 7 is filamentary, sheet-like or threaded, etc. Preferably, the drive module of this embodiment adopts a filamentary memory alloy part 7, so that the decorative flower frame is easy to install and the production cost is low.

[0029] The supporting ribs 5 are used for the ribs of the petals of the decorative flower, and include an operating section 51 and a frame section 52. The length of the frame section 52 is greater than that of the operating section 51. A first rotating shaft 9 is provided at the connection between the operating section 51 and the frame section 52, which is rotatably connected to the peripheral edge of the top plate 2. The supporting ribs 5 can rotate around the first rotating shaft 9. The supporting ribs 5 include but are not limited to sheet-like structures, fishbone structures, or mesh structures, etc.

[0030] The transmission assembly 6 of this embodiment is arranged between the proximal end of the supporting ribs 5 and the slider 4, and includes a fixed rod 61 and a movable rod 62; wherein, the fixed rod 61 is arranged parallel to the supporting slider 3, the upper end of the fixed rod 61 is fixedly connected to the lower side wall of the top plate 2, and the lower end of the fixed rod 61 is connected to the middle part of the movable rod 62 through the second rotating shaft 63, and the movable rod 62 can rotate around the second rotating shaft 63; one end of the movable rod 62 is movably connected to the slider 4, and the other end of the movable rod 62 is movably connected to the end of the operating section 51 of the supporting ribs 5. Furthermore, a first connecting block 511 is provided at the end of the operating section 51 of the supporting rib 5, and the first connecting block 511 cooperates with a first sliding groove 621 provided at one end of the movable rod 62, and the first connecting block 511 on the operating section 51 of the supporting rib 5 can slide relatively along the first sliding groove 621 of the movable rod 62; a second connecting block 622 is provided at the other end of the movable rod 62, and the second connecting block 622 cooperates with a second sliding groove 41 provided at the edge of the sliding block 4, and the second connecting block 622 on the movable rod 62 can slide relatively along the second sliding groove 41 of the sliding block 4.

[0031] The length dimension from the outer side wall of the sliding block 4 to the central axis of the supporting sliding rod 3 is smaller than the length dimension from the inner side wall of the fixing rod 61 to the central axis of the supporting sliding rod 3 .

[0032] Working principle: Figure 1 As shown in the figure, when the spring is in the initial state, the distal end of the slider 4 is close to the lower end of the fixed rod 61 of the transmission assembly 6. At this time, the second connecting block 622 on the movable rod 62 of the transmission assembly 6 is located at the position a in the second slide groove 41 on the slider 4, and the distal end of the supporting rib 5 is close to the middle part of the upper end of the top plate 2. The supporting rib 5 is basically in an upright state, that is, the petal opening and closing mechanism 100 is in a closed state; when the memory alloy part 7 is connected to an external power supply, it produces memory deformation, driving the slider 4 to slide downward along the supporting slide rod 3, that is, slide toward the base 1, and the spring When the spring is compressed and the second connecting block 622 on the movable rod 62 of the transmission assembly 6 slides from position a in the second slide groove 41 on the slider 4 to position b, the slider 4 stops sliding downward. At this time, the distal end of the supporting rib 5 is opened away from the middle of the upper end of the top plate 2, that is, the petal opening and closing mechanism 100 is in an open state, and the supporting rib 5 is basically in a horizontal state. When the memory alloy part 7 disconnects the external power supply, the spring is reset, so that the slider 4 slides upward along the supporting slide rod 3. When the spring is in the initial state, the petal opening and closing mechanism 100 is in a closed state.

[0033] The advantages of this embodiment are: a memory alloy is used as a driving module, so that the slider slides up and down along the supporting slide rod, and the slider drives the supporting ribs to rotate forward or reversely along the peripheral edge of the top plate through the transmission assembly, so that the supporting ribs of the petal opening and closing mechanism can be retracted or opened relative to the upper end of the axis line of the top plate. The structure is simple, the production and assembly are convenient, and the cost is low.

[0034] Example 2

[0035] like Figure 3 and Figure 4 FIG. 1 shows a second embodiment of the petal opening and closing mechanism 100 of the decorative flower of the utility model. Figure 3 and Figure 4 The main difference between the petal opening and closing mechanism of the second embodiment and that of the first embodiment lies in the movable connection structure between the movable rod 62 and the end of the operating segment 51 of the supporting rib 5. Specifically, a third slide groove 512 is provided at the end of the operating segment 51 of the supporting rib 5, and a third connecting block 623 is provided at the end of the movable rod 62. The third connecting block 623 can slide relatively along the third slide groove 512 of the operating segment 51 of the supporting rib 5, so as to be used for the movable connection between the movable rod 62 and the operating segment 5 of the supporting rib 5.
